text: Affectionately known as the âDung Beetleâ, this 1966 VW might look like a rusted, old, junk yard carcass but hidden underneath the hood is a heavily modified, turbocharged 2.3L motor that is more than capable of taking on any competition. Dung Beetleâs motor is a 2332cc turbocharged, air cooled flat four. Considering how little weight it has to haul, itâs more than adequate. Having all that power is one thing, controlling it is another and thatâs one of the reasons AZN decided to team up with Haltech and give the Dung Beetle an EFI overhaul.
